Application filed April 11, 1924. Serial 110/705,?66.

To all whom it may concern:

Be it known that I, WILLIAM ELBERT SExToN, a citizen of the UnitedStates, residing at Baltimore, in the State of Mary- 5 land, haveinvented certain new and useful .an improved construction andarrangement,

1 of burner-piping, manifold and distributing piping for supplying gastothe various burners, or to roups or sets of burners and to so. arrange te piping that a single range or a battery of ranges may'besupplie'd withAnother object of the inve'ntion is to provide an improvedgroup-arrangement of burners and to connect the burners in a group withthe gas-supplyso that all the burners'of a group or only a portionthereof as desired may be operated through the- 4 'medium of a singlevalve.

- A further object of the invention is tov provide an improvedconstruction of gassupply main.

With these, and other objects in view, the invention is illustrated inthe accompanying drawings, wherein,- a

Fig. 10 illustrates a front view of the lower burner-supportingwplates.Fig. 11 shows a vertical sectional detail through the front and rearburner-supporting means, as the same would appear if viewed on the line1111 of Fig. 10. Fig. 12 illustrates a vertical sectional detail of thelower b urner-su porting plates as the same would appear i viewed on theline 1212 of Fig. 10, and

Fig. 13. shows a horizontal sectional de; tail through said lower'burner-supporting plates,the section being taken on the line 13 13 ofFig. 10. a

Referring to the drawings the numeral 12, designates a front plate ofthe range which latter has an upper burner compartment 13; a lowerburner com artment 14, and an oven between the sai lower compartments. I

A door 15, having novel features of construction and operation, butforming the subject of a separate application,"is ivo'tally sustained at16, in suitable brac etupper and provi e a battery or a plurality ofranges in a row, and it is also desirable that the fuel-gas be suppliedso as to avoid a multiplicity of pipes and in such a way that an entiregroup of burners or only certain burners of such group may be used ornot as desired.

It is therefore an object of the present invention to provide a novelarrangement of burners and gas-supply pipes, branches and valves,whereby fuel gasmay be supplied to a set or group of burners, or tocertain burners of a group. of burners by means of .a single controlvalve and without unneces sary use of burners.

With these objects in view, I provide a horizontal upper main pipe 26, alower horizontal main pipe 27 and a vertical pipe 25 which connects saidupper and lower main g v his vertical pipe 25 1s preferably providedwith a valve 10 by means of which gas to the lower main 27 may becut'ofl' without interrupting the passage of gas through the upper main.

he upper main 26 extends horizontally across the front of the range fromone vertical side edge to the other of the range, and said upper main isprovided with a lateral flange 11 at its upper inner side whichflangeextends toward and is flush with the top 21 of the range and seatsclosely against the rim-edge of and around said range-top. By thusseating the flange 11 of the upper main against the rim edgeof therange-top I avoid the formation of a vertical space between said uppermain and the said range-top into which space grease and food materialswould collect.

Each upper main 26 is provided on its under side, and midway between itsends,

with so-called pads 29 and 30 respectively, the pad 29 being locatedbetween two pads 30, and each of the pads 30 has a port extendingdownwardly therethrough for the passage of gas from the main as willpresently be more clearly explained.

To the under side of one ad 30, there is attached one end of a branchpipe 31 while a similar branch pipe 32 is attached to the underside ofthe other pad 30.

The two'branch pipes 31 and 32 extend downwardly from the respectivepads 30 and one of these pipes 31 isturned laterally in one directionwhile the other pipe 32 extends laterally in an opposite direction. Bothof these branch pipes however are located directly beneath the uppermain 26,

" i and extend in opposite directions across the upper front portion ofthe range, as clearly shown in Fig. 1 of the drawing. 1

The branch pipes 31 and 32 are both of novel construction and the pipe31 is provided with a specially-constructed valve 33 while the pipe 32has a similar constructed special valve 34 which valves are interposedbetween and control the passage of gas from the upper main 26 to saidbranch pipes.

It is important to note that the branch pipes 31 and 32, which are oflike construction, are interiorly divided by a longitudinally-extendingpartition 35 whereby to produce two longitudinal chambers or passages 36and 37 respectively in each of those pipes, as may clearly be seeninFig. 3, 4 and 5 of the drawings.

The outer ends of the branch pipes 31-32 are supported in brackets 28which latter also sustain the upper main, and said outer branchpipe-ends are closed in any suitable manner and the longitudinalchambers or passages 3637 are entirely separate and" seatis providedwith a port 39 that communicates with the port 40 in the pad 30 of themain 26 and each seat also has two ports 41 and 42. w.

The valve-seat port 41, (see Figs. 3, 8 and 9) opens into thelongitudinal chamber or passage 36 is the branch burner-pipe 31 or 32while the valve-seat port 42 opens into the longitudinal chamber orpassage 37 in said branch burner-pipe.

It is therefore to be understood that valve port 41 is located at oneside of longitudinal partition 35 while port 42 is on the opposite sideof said partition.

The valves 33 and 34, which are of like construction, each have a port43, to coact with port 39 in the valve-seat and said valves also haveports 44 and 45 to coact with the ports 41 and 42 that open into thechambers or passages 36 and 37.

The valves 33 and 34 are obviously capable of being rotated or turned inthe seats 38 and, .as shown'in Fig. 3, when the valve is in one positiongas from the main 26 may pass through ports .40, 39, 43, 44 and 45, andthrough ports 41 and 42 to both chambers 36 and 37 in the branchburnerpipe; that when said valves 33 or 34 are turned to the positionshown in Fig. 8 gas from the main will pass through ports 40, 39, 43 and44 and then through port 42 to latter position of the valve will cut offthe gas to one-passage or chamber 36 while gas may flow to the otherpassage or chamber 37 By reference to Fig. 9 of the drawing it will benoted that the valve 33 is shown turned to a position where no gas canpass from the main through port 39 and also these passages is controlledby the valvethat both ports 41 and 42 to the passages 36' and 37 of thebranch burner-pipe'are cut off from the gas supply.

The object in providing the two passages 36 and 37 and the valve 33 or34 that will control the flow of gas to one or both or to neither ofsaid passages 36 or 37 is so that,

through the operation of a single valve, certain burners of a group ofburners may be cut off while one or more burners of thesame group may besupplied with gas and allowed to burn.

The burners under the range-top are arranged in groups 23 and 24,therebeing in this instance four burners in each group, although thenumbergmay obviously be varied.

The burners, say burners 23 of the one i group, are connected to thebranch-pipe 31 7 so that some of the burners of the group willcommunicate'with passage 36 of said pipe 31 while other burners of thesame group will communicate with the passage 37 in said pipe 31.

The manner of connecting the several burners of a group with thebranch-pipe 31 is illustrated in Figs. 3,4 and 5 of the 1 drawings andto distinguish certain of these burners from others of the same group in'these particular views of the drawing, I

have designed two of them 23 and the other two are designated 23".

1 By reference therefore to said Figs; 3,v

4 and 5 it will be noted that the burners 23 of the group '23 areconnected to pipe 31 so as to communicate with the passage 36,-

the connection being by means of the ports '46, and the burners 23 areconnected to the passage 37 of thepipe 31 through the ports 47.

In this way some of the burners of group 23 are supplied withgas frompassage 36 of the branch-pipe 31; while other.burners of the same groupare supplied with gas.

from passage 37- of said branch-pipe 31, and the supply of,gas to one orboth of 33, hence, in' the operation of the valve,

23, may be supplied with gas.

' fromthe' main 27 an By means of this construction, the one valve andthe one branch pipe 31 will permit all four burners in the group to beoperated until the range-top is sufficiently hot and then "amanipulationof the valve 38 will operate ;to cut off gas from two of those fourburners but allow the other supply is usually maintained as long as anypart of the range is in operation'this pilot burner will always be inreadiness to ignite the gas turned on through either group of burners 23or 24% Each end of the upper main 26 on a range is provided with aflange 50 (see Fig. 7) having'perforatlons 51 therein so that saidflange may be coupled with a like flange on the main of another rangeand thus produce a continuous main where two, three or more ranges arecoupledtogether in a battery. The main at the end of such a battery willhave a plate attached to its flagge '50 whereby to efiectually seal thaten v The 'lower horizontal main 27, extends from the verticalsupply-main 25, across er burner compartment. 14 where a series of ovenburners 53 are located.

The front wall 12 of the range is -pro-- vided with a lurality ofopenings 54 through which ti inserted so that the inner endsthereof maybe inserted in suitable sockets-55 at the rear as shown in Fig. 11 ofthe drawing. The forward or outer ends 56 of the-burners are flared orof a bell shape and the openings 54, in the front plate 12 of the rangeare larger thansaid flared ends of the burners to permit readymanipulation of the latter e burners may readily belUU - a horizontalplanejust in front of the lowwhen the same are being connected to ordis- I connected fromthe ni pics 57 that project through which gas issupplied.

To provide a proper support for the outer ends of these oven burners andalso to effect a closure of the-large openings 54 in the front plate 12of the range, I provide two. 1

horizontalplates 58 and 59' respectively of a novel construction. J

By reference 'to Figs. 1, 10, 11, 12 and 13 of the drawings it will benoted that these plates 58-59 have rabbeted horizontal edges 60, whichlap=and interlock, and that at mtervals said edges are provided with semental notches 61 which are beveled. When these plates are broughttogether the notches in the edge of the one plate will register with thenotches in the edge of the other and the registered notches willtogether form circular openings with a beveled wall so as-to close aboutthe flared end 56013 the burner and retain the latter in place.

The opposite ends of the plates 58 and 59 are outwardly flanged so as toproject over i and seatclose against the vertical edge of from saidupper the bracket plates 17 and screws 62, rigidly hold the plates inposition.

The edges60 of the plates 58 and 59 arealso provided with seml-circularnotches 63, so that the nipple 64 of a pilot burner may passtherethrough adjacent to or between two of the oven burners 56.

The nipples 57 of the oven burners and the nipple 64 of the pilot burnerare .each connected to the lower horizontal main 27, and each of thesenipples has its own control valve such as indicated at 65 in Fig. l.

The lower main 27, of one range like the upper one 26, is intended to becoupled to a like lower main on the next range in a.

battery of ranges, or be closed by a blank plate as desired.

From the foregoing explanation it will be understood that the controlvalves 33, 34: and 49 to the upper group of top burners are closelylocated at the center of the range wherethey are readily accessible toturn on or oil' as desired and that the gas to the two groups of topburners flows fromthe upper main into the branch pipes and to one orboth passages 36 and 37 as desired.

It will also be understood that the supply of gas to the'lower ovenburners is taken from the lower main directly to the burners themselvesbut is controlled by separate valves so that any one or more of saidlower burners may be utilized at a time.
